Gorgonocephalidae
Gorgonocephalidae is a family of basket stars. They have characteristic many-branched arms. Gorgonocephalidae are the largest ophiuroids ('' Gorgonocephalus eucnemis'' can measure up to 70 cm in arm length with a disk diameter of 14 cm). Systematics and phylogeny The family is divided into the following genera: Fossil record of Gorgonocephalidae dates back to Miocene The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and mea ....Kroh, A. 2003.

Basket Star
The Euryalina are a suborder of brittle stars, which includes large species with either branching arms (called "basket stars") or long and curling arms (called "snake stars"). It is sometimes listed as the order Euryalida. Characteristics Many of the species in this order have characteristic repeatedly branched arms (a shape known as "basket stars", which includes most Gorgonocephalidae and two species in the family Euryalidae), while the other species have very long and curling arms, and go rather by the name of "snake stars" (mostly abyssal species). Many of them live in deep sea habitats or cold waters, though some basket stars can be seen at night in shallow tropical reefs. Most young basket stars live on specific type of coral. In the wild they may live up to 35 years. They weigh up to Like other echinoderms, basket stars lack blood and achieve gas exchange via their water vascular system. The basket stars are the largest ophiuroids with '' Gorgonocephalus stimpsoni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brittle Star
Brittle stars, serpent stars, or ophiuroids (; ; referring to the serpent-like arms of the brittle star) are echinoderms in the class Ophiuroidea, closely related to starfish. They crawl across the sea floor using their flexible arms for locomotion. The ophiuroids generally have five long, slender, whip-like arms which may reach up to in length on the largest specimens. The Ophiuroidea contain two large clades, Ophiurida (brittle stars) and Euryalida (basket stars). Over 2,000 species of brittle stars live today. More than 1,200 of these species are found in deep waters, greater than 200 m deep. Range The ophiuroids diverged in the Early Ordovician. Ophiuroids can be found today in all of the major marine provinces, from the poles to the tropics. Basket stars are usually confined to the deeper parts of this range; Ophiuroids are known even from abyssal (>6,000 m) depths. However, brittle stars are also common members of reef communities, where they hide under rocks and even w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gorgonocephalus Eucnemis
''Gorgonocephalus eucnemis'' is a species of basket star in the class Ophiuroidea. It is found in circumpolar marine environments in the Northern Hemisphere. The scientific name for the genus comes from the Greek, ''gorgós'' meaning "dreadful" and ''cephalus'' meaning "head", and refers to the similarity between these basket stars and the Gorgon's head from Greek mythology with its writhing serpents for hair.GORGONOCEPHALUS!!

Astrophyton
''Astrophyton muricatum'', the giant basket star, is an echinoderm found in shallow parts of the tropical western Atlantic and throughout the Caribbean Sea and the Gulf of Mexico. It is the only species in the genus ''Astrophyton''. During the day, it curls up into a tight ball shape to protect itself from predators. At night, it climbs to an elevated point to feed by extending its intricately branched feeding arms in a bowl-like shape in order to snare passing plankton and other organisms from the current. Description The giant basket star is a very large echinoderm that can reach a diameter of nearly a metre when its arms are fully extended. It has a central disc and eight slender, flexible arms that repeatedly divide to form a fine-meshed net-like structure. The colour is generally brown or black. Distribution and habitat This basket star is found in warmer regions of the western Atlantic Ocean, the Caribbean Sea and Gulf of Mexico. Its range extends from Cape Lookout in Nor ...
